Industry-Leading Patent Portfolio Adds Fifth New Patent of 2015, With Five More Patents to Issue Soon and A Patent Pipeline of More Than Two Dozen Pending Applications

Company on track to be issued more than 20 patents this year

Reston, Virginia (PRNewswire) –June 8, 2015 – Global Tel*Link (GTL), the leading provider of correctional technology solutions, announces the issuance of United States Patent No. 9,014,355, Telecommunication Revenue Management System, the fifth patent issued to GTL in 2015, and the latest in a series of more than 20 patents that the company anticipates will be issued to it by the end of this year.

The patents most recently issued to GTL are at the leading edge of the company’s portfolio of correctional technology, including investigative services, payments, new three-way call detection, and telephone voiceprint, – all representing innovations and designs from GTL’s industry-leading team of engineers and developers.

“We are extremely proud of our software development and engineering teams, who have together created the innovative, patent-worthy solutions that keep GTL at the forefront of the industry – both in terms of products and the overall quality of our intellectual property,” said Brian Oliver, CEO of GTL. “Our patents and patent applications reflect GTL’s investment in research and development into corrections technology, the great wealth of creative talent that we employ for our customers, and, perhaps most of all, the company’s continued commitment to create products that improve both security and ease of communication.”

In addition to the five patents issued to GTL so far in 2015, the United States Patent and Trademark Office (USPTO) has notified the company that five additional patent applications have been granted and will issue shortly, while at the same time GTL continues to add to its many pending patent applications and is looking forward to the issuance of as many as 20 new patents in 2015, based on current trends. The company’s portfolio has been carefully groomed to focus on the latest developments in the market’s need and the latest technology, with the understanding that in the current environment patents may be subject to challenge.

“GTL is dedicated to developing cutting-edge technologies that not only meet the current needs of our customers, but also foresee what needs are likely to arise in the future,” Oliver added. “In that same way, we intend to protect those ideas and have built our patent portfolio on a foundation of innovation and integrity. As a consequence, we have patents that matter – creative, meaningful ideas presented honestly and with pride.”
